This is the place From where I bought my Zero and here's some ideas what to use it for. Check #4 and #8!LINK

there's a lot of things to do with pi's ...back in 2015, i made both a pi2b paired with a motorola lapdock to myself and also a pi zero paired with a lapdock for one of my friends ( he got the zero for free with the pi magazine ). instead of using the traditional choices of different plugs, long cables, converters and adapters i soldered the wires to the PP points of the boards. here's my convertion https://www.raspberrypi.org/forums/view ... &start=825

ofcourse a zero board can be used for a lot of purposes, but i think the real fun starts with pi2 or pi3, where almost everything is onboard. the zero lacks a bit, because you have to add components. still i think pi zero is a funny little thing for programming purpose.

I have gone from Volumio to Rune on a P12 with a HDMI audio extractor. But when I started listen to music, now from Rune, I felt the quality had dropped considerably. I'm having to use the software volume control in the OS and run it about 30% because my Oatley K272A HP has no volume control. What I have come to realise is that Volumio's software volume control is far better than Rune. Rune does warn you that you will lose resolution if you use the software control. Not only did I lose resolution but dynamics.

To fix this I added a pot to my portable HP amp. Yes the music is back, on the Pi2 with the HDMI audio extractor and its sounding fab again. Because I had to do some open hart surgery on the K272A I notices two things I had forgotten. Firstly I used all three-nines 0.7mm pure silver wire as hook-up wire throughout and secondly I had heavily modded the cct. brd. to support 18V (and not 9V) working. Well it certainly has paid off. The sound is extremely good on my Sennhieser 700s.
